In this paper, we introduce a method which makes it possible to rapidly and accurately determine the penetration depth as a function of temperature for superconductive thin film samples. A key feature of the approach described here is that it is deri

In this paper we discuss passive vibration isolation systems for ultralow temperature gravitational radiation detectors, using a detector at Stanford University as the primary example. We review the basic theory of such isolation systems and describe

Preliminary measurements on high-T/sub c/ superconducting resonators are reported and why they are attractive candidates for incorporation in low-noise oscillators is discussed. Some of the important contributions to oscillator noise are reviewed and

We describe a magnetic induction probe capable of rapid measurement of the critical current densities of superconducting thin films in a noncontacting, nondestructive fashion. The use of an iron core enables us to generate field levels at the sample

In order to extend earlier work on in-situ off-axis sputtering to larger areas, the authors used two facing targets in the off-axis configuration to produce YBa/sub 2/Cu/sub 3/O/sub 7- delta / superconducting films with low microwave surface resistan

The resistive losses near 10 GHz are measured at 4.2 K for ten c-axis-oriented ${\mathrm{YBa}}_{2}$${\mathrm{Cu}}_{3}$${\mathrm{O}}_{7}$ thin films deposited in situ on MgO substrates. The losses range from 16\ifmmode\pm\else\textpm\fi{}3 \ensuremath

High quality superconducting films of YBa 2 Cu 3 O 7− x were deposited in situ using single target 90° off-axis sputtering. We have investigated their superconducting DC and RF properties, their normal state properties, and their microstructures.

A simple method for the evaluation of microwave surface loss of superconductive samples is discussed. The method allows the evaluation of small (∼1 cm×∼1 cm), flat samples over a broad range of temperatures. It can accurately characterize sample

A simple and accurate method of calibrating the response of a resonant‐mass gravitational wave detector to an impulsive signal is discussed. The procedure automatically includes the effects of the detection electronics chain and any filtering algor
